Difference in action sites between mecamylamine and hexamethonium on nicotinic receptors of sympathetic neurons;

Na, K and Ca currents and other electrophysiological characteristics of cultured neonatal rat superior cervical sympathetic neurons were studied using whole cell clamp technique.

Effects of GDNF and substrate on superior cervical ganglion sympathetic neurons in vitro;

Aim: To investigate the roles of acetylcholine (ACh) receptors in the rapid effects of corticosterone(CORT) on the presympathetic neurons in the rostral ventrolateral medulla (RVLM) of rats,and study the non-genomic mechanism of glucocorticoid(GC)in the integration of sympathetic cardiovascular activity.

Electrophysiological study of presympathetic neurons in the rostral ventrolateral medulla in rats;

Effect of acetylcholine on the discharge of presympathetic neurons of the rostral ventrolateral medulla of rats;

The presympathetic neurons in the area mono synaptically innervate sympathetic preganglionic neurons,though which take the control of sympathetic outflow.

Study on the localization of sympathetic efferent neurons innervating hepar of chicken;

By retrograde tracing with CT-HRP,the localization of the sympathetic efferent neurons innervating pancreas of chicken was studied.

CB_HRP was injected into one_sided kidney,the results show: the labelled cells of sympathetic postganglionic neurons were found in T_6 to L_3 segments of sympathetic trunk ganglia in the same side of the operation.
